. To all whom it may concern:

' of the keys much more re idily than theobject the Provision of a mechanism under Be it known thatl, ERL V. BE IiLS, of Boston, in the county of Sufielk and State of:

ability of the operator to se ect and depress them successively-that is tosay, the-greate est s eed at which the operator can work is not y any means the capacity of theme chine, since the latter may be operated at a speed several times greater than that of the most rapid operator. Consequently l have fo11nd=it-poss1ble to utilize a single linot pc or type-setting machine under the contro of a plurality of operators, whereby one machine may be used by said operators for several com ositions. A,

T e present invention therefore has for its the control of a p urality of operators for actuating a single linotype, matrix-making, or type-setting machine whereby said 0 erators may at their leisure simultaneous y Work upon se arate compositions independently of each ot er, and While, as said, my invention is designed more particularl for linotype or typesetting machines at t e same time it may be employed in connection with any machine controlled by a fingenkey operation.

The invention consists oi a single duplicat- 'ing or key-actuating mechanism ada ted to be arranged in operative relation to t e keys of a linotype, type-setting, matrix-m'akin or other machine and a plurality of indepen cnt composin mechanisms by means of which the dup icating mechanism may be. ac-- tuated to effect the operation of the last-mentioned machine. Each composing mechanism is under the control of a single operator and is provided with a plurality of keys similar in number to those of thelinotypeor'typesetting machine, and the duplicating meh amsm is likewise providedwith Correspondillustrates a plan View of the machine.

ing actuating members to o crate on the keyboard of-the linotype-mac ine. Each composing mechanism includes in addition to the keys one or more selectors controlled thereby, a dummy or mechanical line consistllw di a plurality of actuators under the control of a the selecting instrumentalitics, and transferrin or repeating devices connected with the uplicating mechanism and controlled by the dummy for causing the actuation thereof. By depressing-the keys of the com posing mechanism in a predetermined order they cause the actuation of the selector' and the selection of the actuators in said order, this being accomplished at an desired s eed by the operator simultaneous y ,With an independently of the work being accom lished by another operator on a similar se ectingmechanism. When an operator has thus selected and arranged a plurality of actuators of the, dummy in a certain order, each actuator representing a certain character or symb'ol, according to its'set osition, the trans ferring deviceis operate to cause the actuat-ion of the duplicating mechanism and the consequent operation of the linotype, type-- setting, or other machine equipped with a keyboard.

' As will be readily understood, mechanism must be provided for preventing the simultaneous operation of two re eating or transferring devices, and hence t e present invention includes means whereby when one of the transferring devicesis operating the other is rendered inoperative.

I have not illustrated in the present patent the mechanism for separating the slugs or lines of type in the linotype or type-setting machine as said mechanism is fully illustrated and described and forms part of the subject-. matter of my Letters Patent No. 696,360, dated March 25, 1902.

'Fmmew0r7c.Referring to the drawings, which illustrate one embodiment of the invention, to the. details of construction of which it wvill be understood, as previously stated, I am not limited, a machine is shown adapted for use by two operators. It isfprovided with the bed 100, supported by end standards 101. Rising from the bed are three bearing-brackets 102 103 104, which are utilized to receive and supporta portion of the operative mechanism of the machine. As previously stated, said machine includes a duplicating mechanism, the transferring mechanisms, and the composing mechanisms. The composing mechanisms are placed in a line on the bed, with the keyboards separated far enough apart to prevent the o erators from interfering with each other, an the du plicating mechanism is arranged for convenience at the rear of the machine.

Driving mechanism-The driving mechanism includes an electromotor 105, suspended underneath the bed 100 and having on the armature-shaft a small pinion 106, intermeshing with. and driving a'gear 107. The latter is journaled on the stud-shaft 108, rojecting from a bracket 109, depending om the bed. The said gear 107 has secured to it a pinion 110, intermeshing with and driving a large gear 111, journaled on a stud-shaft 1121, proj ecting from thebed 100. The gear 111 is connected with the gear 112, the latter being composed of a toothed-rim adjustably secured to a hub, as shown in Fig. The gear 112 is rigidly secured to a ma n shaft 113, which is journaled in the uprights or bearings 102 103 104.

Composing mechamsm.Each composing mechanism is similar to the others and includes a keyboard selector-slides, and electromagnetic. mechanism, a dummy formed of actuator-rings, mechanism for feeding the actuator-rings, resetting mechanism, and electric circuits.

- Keyboard.-The keyboard of each composing mechanism is supported by brackets 114, extending downward and forwardly from the under /side of the bed 100. The keys are arranged in banks and are e ch provided with a knob 115, on which is pr ted or indicated a letter, numeral, punct ationmark, or other symbol, such as usually found in linhtype, type-setting, type-writ ng, or other machines,.'a spindle 116, and a cad 117. The keys are supported by a frame (indicated as a whole at 1 18) and having the inclined top late 119, said keys being normally raised by a coiled spring 120. (See Fig. 4.) The frame 118 is provided w th the intermediate plate 121, which, with the inclined plate 119,forms a guide for the reception of the spindles 116 of the keys, the hea s 117 being located below the said late 121.

closed, said head being in reality a switch op- .erabl'e at the will of the operator. Along each row of switches is a metallic bar 123, cpertured to receive a contacting spring 124, which is held yieldingly in an operative position by a pin 125. Each bar 123 is insulated from the plate 121. Underneath each row of keys is a single cross-bar 126, of non-conducting material, such as wood." Said cross bars operate to limit the downward move ment of the keys, and to said cross-bars are secured spring-contacts 127, there being one contact for each head 117. Said contacts are arranged opposite to the ends of the pins 124, and when the keys are in an elevated osition the circuit is closed between them; ut when the key is depressed the said circuit is broken. Each one of the contacts 127 is in a separate branch circuit including a wire 128,

the cross-bar 123 being connected in multiple with ameturn-wire 129. Connected to the lastfrncntioned wire there is a switch 130,

located: on the end of the keyboard for breaking the maincircuit when the machine is not being used. From this descri tion it will be seen that when the keys are a raised and in inoperative position all of the branch circuits are closed; but immediately upon one of the he '5 being depressed the branch circuit th refor is immediately broken, for a purpose to be subsequently explained. The heads 117 are beveled to permit the easy movement thereof past the contacts 124 and 127.

Selector mechanism-The .selectormagnets, of which any number may be employed,

though I prefer two, for reasons to be explained, are controlled by the key-circuits,

and they operate to select and actuate slides in the same order in which the keys are depressed. The selector-slides are edual in number to the key-circuits, and they are arranged in a circle about a common center. These slides control a plurality of actuators or rings (which constitute the dummy) rotating upon an axis coincident with said common center, and-they stop the rings at predetermined points in their rotation, (causing them to remain fixed in the positions in which they are stopped,) upon a suitable support splined to receive them. Each time a selector-slide is actuated by the breaking of a key-circuit, as will be explained, it stops a rotating ring at a certain point in its rotation corresponding to the location of the slide.

Assuming for the sake of explanation that each rotating ring of the dummy bears upon its periphery all of the characters of the typefont, then by stopping said rings in succession with reference to a fixed line the characters in a certain line may be caused to indicate the word, phrase, or sentence. Instead of bearing alphabetical characters, however, each ring carries a finger or projection, and

.the location of thatfinger when the ring is stopped upon its support depends upon the selector-magnets to be described.

rality of slides equal in number toand arranged similarly to the selector-slides, and each of them is connected with a rod or member located above a' key of a linotype, typesetting, or matrix-making machine.

' The slides of the duplicating mechanism are-actuated by electromagnets similar to the In circuit with the said magnets are two interrupters, which may be moved along a line parallel to the axis of the cylindrical support upon which the rings are placed, being fed with a step-by-step movement. Hence when a line has been composed the cylindrical support for the dummy is set in motion, and as it rotates the interru tin devices lare fed along and are engaged y t e fingers'upon the successive rings of said dummy. The duplicating-magnets rotate in unison with the rings and their support and in operative relation to the transferring-slides, so that the engagement of an interrupter by a fin er on the ring causes the actuation of the s ide in the duplicating mechanism corresponding to the selector-slide which caused the placing of that ring in that particular location upon said support.

Selector-slides.-As the composing mechanisms are similar, I shall describe only one of them. Secured upon the bed are two u rights or supports 131 132, each of'which is in the shape of a ring. (See Figs. 7, 10, 11, and 15.) The shaft 113 passes through said standard, the apertures of which are relatively large. The annular upright 132 is proported by said flange and by the nnular upright or support 131 are a plurali y of actuator-slides 134, arranged at equal radial dis tances around the shaft 113 and lying parallel thereto. Said selector-slides are shown in detail in Figs. 13 to 16, inclusive, each being 'vided' with a h internal flange 13;, and supconstructed of a long narrow metallic strip having at its rear a cylindrical pin 135 with a head 136, said pin passing through the fiange 133. Coiled springs 137 surround the said pin and bear against the heads 136 and the flange 133 to hold said slides normally rearward. The front end of each slide is provided with a laterally-projecting finger 1 38, arranged radially of the shaft 113. The annular upright or support 131 is provided with apertures 139 to receive the slide'and also with radial notches 140 in its front face to receive 'the fingers 138. Each finger is provided with a shoulder 141, by rheansof which the finger is held in an inoperative position,

there being, however, a leaf-spring 1 4-.4 formed on or secured to said slide and bearin against the inner wall of the aperture 139 to orce the finger radially inward when the slide is moved compound ma net.

forward to disengage the shoulder 141 from the wall of the support 131. I In order to position each slide as it is moved into 0 erative position, it is provided with a bevel 143, which engages a bevelwall 144 of the aperture 139, as best shown in Fig. 17. At its outer end each slide is provided W th a pin or projection 145 for a purpose to be subsequently explained.

The heads136 and the slides form a circle, and they are in position to be engaged and thrust endwise by selectors, which I shall now describe. Rigidly secured on the shaft 113 is a carrier 146, (see Figs. 5 and 7,) which is rotated thereby at a high rate of 'speedto wit,'from two hundred to three hundred revolutions per minute. Said carrier is substantially in the shape of a disk or wheel except that it is provided with radial sockets 147 for the reception of electromagnetic devices. Each magnet comprises two coils 148 149, wound about the hollow core 150, arranged radially of a carrier. The coil 148 is considerably longer than that at 149, so that the -magnetic strength thereof is much greater than that of the latter. The armature 151 for the attracting magnet or coil 148 is connected by a rod 152, assing through the'hollow core 150, with t e armature 153 for the holding or smaller magnetic coil 149. The two coils which thus compose the two-part magnet are secured within a cylindrical casing 154, which is journaled in a brass bushing or box 155, secured in the socket 147. The casing and the core are both made of SW eedes iron. The end of the casing is flanged at 156 and overlaps the end of the box or bushing 155 to prevent endwise movement of the Secured to the portion of the casing w ich projects beyond the bushing there is a bevel-gear 157, which intermeshes with a circular rack 158, attached to the flange 133 of the support 132, so that when the carrier 146 is rotated the magnets are revolved about the shaft 113 and also are rotated on axes radial of the said shaft.

Secured upon the head of the pinion 157 are four insulated collector-rings 158, 159, 160, and 161. (See Fig. 9.) On the end of the larger coil there are laced layers of insulating material 162, an through said layers and through the collector-rings are passed binding-screws 163, each binding-screw being attached to one of the collector-rings and being insulated from the other rings. The coils of the smaller magnet are connected with the rings 158 160. by wires passed inside of the casing and connected with the screw 163, and

' the collector-rings 159 and 161 are connected with the larger coil of the magnet. Brushes 163, 164, 165, and 166 are in electrical contact with the collector-rings 158, 159, 160,

and 161, respectively, there being a set of collector-brushes for each com ound magnet.

By means to beex laine when the circuit is broken by one o the keys through thesmaller end of the magnet the larger ortion is energized to an increased extent an draws the armature 151 to it, causing it to rotate therewith, constituting, as it were, amagnetic clutch.

Normally the armature last referred tois outv of alinement with the head of the selector-slide but when it is moved toward the magnet it is brought into alinement there:

with. The said armature is substantially circular in plan view except that it is provided with two oppositely-projecting fingers or selectors 167, either of which may engage'the 1 end of one of the selector-slides and move it longitudinally into operative position. The circuit is then almost instantly restored in the smaller end of the magnet, and as the armature rotates the cam 168 on the upper endof rod 152, which rests upon a stationary cam 169 on the perforated support, rides up on 171 on the armature engages just as said ar- I mature completes one half-rotation about its own axis, and to insure the full half-turn of the armature and the engagement of the'two stops there is secured to the hub of the armature a friction idler 1711, havin shoes of yielding frictional material adapte to'engage the end of the support 132 after the armature has left the ma net to such an extent as to weaken or brea the magnet-driving power. These pins hold the rotating armature against further movement until the circuit through the smaller end of the magnet is again broken. The attraction of the armature 153 at the smaller portion of the rotating magnet tends to hold the two stop-pins 170 171 in firm and constant engagement, it being essential that the armature;151 when it be ins its rotation should always start at a fixe point. In order to carry the current from each of the depressed keysin the keyboard to the magnets on the rotary carrier, I employ a stationary commutator, the sections of which are mount-- ed upon the support 132, thelatter being'provided with an annular flange .172 for this purose. The commu tor'- sections are indicated at 173 and areas many in number at least as there are keys in the keyboard and asthere are-selector slides. Said sections are arranged in a groove formed by the-flange and by a ring 174, which is secured thereto, the groove being dovetailed and the end portions of the sections being similar in shape, whereby they are held a ainst movement. The

sections are not ony insulated from each compound magnets, and hence as. the sections of. the commutator are placed very closely together. the circuit through the smaller, ends of the. magnets will be practically continuous unless onset the keys be depressed to break it, and inasmuch as the carrier is rotated ata speed of about three hundred turns per min ute it is impossible'for an operator to depress a key and release it 'before one or another of the'brushes will have swept-across the section of the commutator with which thekey is connected and will have meadow breaking of the circuit through thesrriitller endof one of theme ets.'

' sha l hereinafter describe the electric circuit more in detail, it sufiicing for the present toistate that each time a key is depressed to "breakthe circuit through the commutator- .-..5 sect ons connected therewith upon arrival of a, the carrier into juxtaposition to said Section the circuit is immediately broken through the smaller end of one of the magnets ahd t e rotating armature is -im mcdiately drawn into contact with the larger end of said fiiagnjetand rotated far enough to-cause it to e a era selector-slide.correspondingtothe a d 'ey'Qf 'At the same time-that the circuit is broken through the smaller end of one com d magnet the magnetic energy of the end of said magnet'and the smaller end 5125?;

. lml y to the head of the selector-slide,'so that but a slight rotative movement is necessary to cause the actuation of the latter.

The dumrity-The dummy consists of actu ators, the osition of each of'which is determined by t es'elector-slides. Sai'd actuators are indicated at 190 and are journaled or supported upon a large sleeve 191. At its ends the sleeve supported'upon a second sleeve or bushing 'l92. At one end the bushing 192 is supported loosely upon the shaft 113.by a collar 193-, (see Fig. 7,) and at its,other end it is rigidly secured to a bushing 194, loose on the. shaft 113. (See Fi 34.)" clutching mechanism, which I sha 1 describe, is em; ployed for connecting the bushingand sleeve 1.92" with the constantly-moving shaft at a certain time. The outer sleeve or support is free to slide relatively to the sleeve '1 92, but is held from rota tive movement relatively thereto b a key 195, (see Fig. 10,) which is secured to t e Sleeve 192 and extendsthrough a slot in the sleeve191. The projectingedge ofthe key is'narrow, and it projects but a short distance radially from the pcriphcry of the sleeve '191. The cylindrical s cove 191 is supported atone end by a collar 197 on the bushing or sleeve 192, as shownin Fig. 13, and at its other end it is provided with an inwardly-promot ing flange supported by the said sleeve 192. The last-mentioned ends of the support 191 has a grooved external flange 198, with which is engaged the means for moving the support relatively to the sleeve 192'.

. By examination of Fi 13 it will be observed that the key or spiine 195 ends in the plane of the front face of the support, whlle the cylindrical support for the rings may slide considerably beyond the said face, so as to lie within the shell formed by the selectorslides.

Each of the rings 190 is journaled upon the c lindrical support 191 and is free to rotate t ereon unless engaged with the spline 195', and to permit them to. be engaged by said spline and'held stationary each ring is formed with aplurality of internal notches 199, adequate to receive a projecting edge of the spline, There are as many notches at least 1n each rin as there are keys in the keyboard and as t ere are selector-slides, and the position at'which any one of the rings is held determines the particular key in the linotype ortype-setting machine which is depressed by a du licating mechanism. Each ring is pro- V1 ed with a disappearing spring-pressed inc r'nber'or trigger 200, pivoted in a socket provided for it, as shown in Fig. 12, itbeing held so thatits end projects beyond the periphery of the ring by a spring 201; The trigger is adapted tobe engaged during the rotation of the ring while it is to the right of the spline in Fig. 13 by the finger 138 of any one of the selector-slides 134, and when it IS thus held against rotation the cylindrical support 191 is moved longitudinally to engage the ring Withthe spline. As I have stated, the selector-slides are equal in number to the ke 's in the keyboard, and the notches are 0 the same number, so that when one of the keys is'depressed the sclectorslide which corresponds thereto is moved to operative position by the means previously described, whereby the ring is checked in its rotation and is engaged with the spline, the position of the ring and trigger upon the support being determined by that particular selector-slide which en-gages it.

The mechanism for rotating the rings con sists 'of a roll 203 of yielding frictional material such as ruhber, leather, or the likesecured upon a hub 204,thc latter being formed with the straight spur-pinion 205. (See Fig. 11.) The hub 204 is journalcd in a'bearing 207, formed on or secured to the upri ht 131. I To the end of the bushing is attache a han- L dle 208, by means of which it may be rocked to adjust the roll 203 towaid or from the rings on the cylindrical support 191; J ournaled in the bushing is the smooth end. of a screwbar 209, whose'other. end is journaled in the upright 102. (See Fig. 2.) Upon said screwbar 1s rigidly secured alarge gear 210, inter-i driving a smaller pinion meshing with and 211, journaled on said shaft 212, supported by a bracket 213, projecting out from the 1 bearing 207. Tlie pinion 211 is connected to a lar er gear 214, intermeshingwith and driving t e inion 205. The screw-shaft 209 is rovide on its opposite end, with a gear 215,

, mtermeshing wit and driven by a gear 216 from the shaft 113. When. the machine isin 0 eration, the roll is rotated quite rapidly by t e gearing described androtates'those rings 1 with which it is engaged. It w be observed from Fig. 11- that the said ml is so located that it engages several ofitl' e'i'ings which are in juxtaposition 'to the Third-56f" the spline, said roll being located so .thatjits front face is in the plane of the front face of the annular support or upright 131.

Mounted in rackets-220 221, supported by the lipright 102 andthe annular upright or support 131,lt l'1ere is a grooved rockshaft 222. (See Fi 29.)- Keyed on therock-shaft so as to sli ethereon is a carria'ge 223, having a pivoted pawl 224. Said carriage has a head 225, extendiilg into the .not shown exceptin Fig. 1.

groove in the end 198 of the cylindrical support 191, and said carriage is likewise connected by steel ribbon 226,.passing over an idler 227 with a powerful co1led-spring-228, arranged in a suitable socket 229, secured to the end of the machine. (See Fig. 2.) The spring for the other selector mechanism is arranged horizontally behind thebed and is The ribbon 226 .is connected with the carriage 223 by a shackle 230. The pawl 224 is adapted to be engaged successively -with either of two ratchet-bars 231 or 232, one of which is stationary and the other of which is adapted to longitudinally move the distance of one teeth. The stationary ratchet-bar 232 is secured to the brackets 22 0 221, and it is provided with a lug 233 at each end extending into a'slot in the end of the movablebar 231. The said movablebar 231 is connected withthe bracket .220 by a coiled spring 234'. The tooth of the pawl is just wide enough to engage either of the bars 231 or 232, and it is moved succesw sively into engagement with them by the rock-shaft 222. Under normal condltions 9a,- the pawl is engagedlwith the movable bar, the latter in such" cases beingdrawn by the ribbon 226 to the end of its movementlongitlb' dinally, so that when the shaft 222 is rocked *to move the pawl into engagement with 'the bar 232 the spring 234 draws the bar 231 back one tooth, and hence when the shaftis rocked in the. opposite direction to return the pawl .224 into engagement with the ratchet-bar 231 it will engage the tooth next to the one :00 previously e aged and the said bar 231 A will yield the istance of one tooth,-whereby the carriage 223 and the cylindrical support 191 will be advanced one step.

It is desirable to adjust the carria e with ios relation 'to the rack-bars, and this is one by means of an adjusting-screw 235, which is passed throughthe free end of the pawl 224 and is adapted to engage the bar 232 to limit the movement of the bar.

. IIO The mechanism for rocking the shaft in-.

. eludes an arm 236, secured to said shaft, and

an electrically-controlled cam 240 for engaging' the said arm. The rock-shaft 222 is normally held in .position tonause 'the engage- ,ment of the pawl 224 with the movable ratchet-bar by a spring 237, coiled about said bar 232.

Rigidly secured uponthe'shaft 209 is a gear 238;.which intermeshes with and is driven 1 20 y a large gear 239 in the shaft 113.- (See Fig. 26;) t will beremembered that the last-mentioned shaft rotates' continuously, and hence the gear 238 is likewise driven continuously when the machine is in operation.

Bymecha ism which I will now describe the cam 240 is permitted to make-a sin le rotation and is then stopped automatica y, the stoppin and starting of the cam being contro led y an electromagnetically regulated 1 o
